ATTACHING TI-IILLS TO CARRIAGES.

Specification of Letters Patent No. 29,614, dated August 14., 1860.

To all whom "it may concern:

Be it known that 1 E. H. PLANT, of Plantsville, in the county of Hartford and State of Connecticut, have invented a new and Improved Mode of Attaching the Thills of Vehicles to Their Axles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is an inverted plan of my invention. Fig. 2 is a section of ditto, taken in the line as, 00, Fig. 1. Fig. 3 is a sectional view of the same, taken in the line y, 3 Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to obtain a simple means for attaching thills t-o axles, whereby all wear may be compensated for; or the parts readily adjusted so that they may be kept snugly in contact, and the disagreeable rat-tling attending a looseness or play of the coupling, with the consequent wear and tear avoided.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A represents a portion of the front axle of a vehicle, and B is an ordinary clip, by which a plate 0, is secured horizontally to the axle, the ends of the clip passing through the plate, and having nuts ((4,) on them. The front end of the plate 0, is made of concave form, as shown at a, in Fig. 1.

D is a metal strap, bent so as to have two parallel sides or bars I), 7), between which the plate C, is fitted, one bar Z), being above, and the other below the plate 0. Each bar 5, has a slot cZ, made through it, and a wedge or key E, passes through the slots 0, 0, (Z, as shown clearly-in Fi 2. The slot (Z, of the plate 0, does not register precisely with the slots 0, c, of the bars I), b, the former being rather farther back or nearer the axle A, as shown in Fig. 2.

F represents a metal bar, which is attached to the back part of one of the thills, said bar having its back end divaricated or forked and a pintle or bolt G, fitted or secured between them. This pintle or bolt G, is placed between the front end of the plate C, and the strap D, and is made to fit snugly therein by drawing down the key E, said key in consequence of the relative position of the slots 0, 0, (Z, drawing the strap D, backward. The key E, is thus adjusted by means of a nut H, which is fitted on a screw 6, formed on the lower end of the key E, and the nut is prevented from casually moving or turning by means of a bar I, which is fitted at its back end on one of the ends of the clip-the front end of the bar I, being slotted or forked so as to embrace the nut H, as shown clearly in Fig. 1.

From the above description it will be seen that if in consequence of wear the pintle or bolt G, has any appreciable amount of play between the plate 0, and strap D, the pintle or bolt may be readily tightened by turning nut H, the bar I, being first freed from the nut. All rattling and play may therefore be prevented.

The device is extremely simple and may be constructed at a very small cost by any ordinary blacksmith, and may be readily repaired or put in order in case of any parts becoming worn or deranged by long use.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is

The employment of the wedge E, screw 6, and nut H, in combination with the axle A, slotted plate C, strap D, bar F, and pintle G, as herein shown and described so that by depressing the wedge E, the strap D, with pintle G, will be carried toward the plate G, and the bearing of the pintle Gr, between the strap D, and the end of plate C, will be tightened all as set forth.
